Title:	Philippine Roll-on/Roll-Off (RoRo) Connectivity and Transport Data
Version:	0.1.1
Description:	Provides the first standardized dataset of the Philippines' Roll-on/Roll-off (RoRo) shipping network, reflecting the 2024-2026 operational state. It digitizes fragmented records from the Maritime Industry Authority (MARINA) and Philippine Ports Authority (PPA) into a unified framework for transport modeling. The package includes 108 bidirectional provincial links across the Western, Central, and Eastern Nautical Highways, complete with GADM-standardized naming, geospatial coordinates, and metrics such as distance, travel time, and vessel frequency. Methodology follows Anselin (1988, ISBN:9024737354) and LeSage and Pace (2009) <doi:10.1201/9781420064254> for spatial weight construction. Data sources include "MARINA Inventory of RoRo Routes" https://marina.gov.ph and "PPA Port Statistics" https://www.ppa.com.ph/ppa_statistics. Designed to support research in economic geography and disaster-response logistics.

Examples

library(roroph)
library(dplyr)

# Load the network data
data(roro_routes)

# Example 1: Basic Analysis of Connectivity
# Calculate the average passenger capacity per highway system
roro_routes %>%
  group_by(highway_type) %>%
  summarise(mean_pax = mean(pax_cap, na.rm = TRUE))

# Example 2: Spatial Adjacency Logic (Anselin/LeSage framework)
# Filter for the Western Nautical Highway (WNH) hubs
wnh_hubs <- roro_routes[roro_routes$highway_type == "Western", ]

# Simple validation check of coordinates for spatial weight construction
if (requireNamespace("sf", quietly = TRUE)) {
  library(sf)
  # Check if coordinates are within the Philippine bounding box
  bbox_check <- all(wnh_hubs$from_lat > 4 & wnh_hubs$from_lat < 21)
  message("Coordinate validity: ", bbox_check)
}
